Temperature control type monomer reactor

Abstract

The invention provides a temperature control type monomer reactor which is preferably made of aluminum alloy or made of stainless steel or copper, and the temperature control type monomer reactor is used for a carbon monoxide preferable methanation reaction of reactant gas which is to be supplied to a fuel battery system and obtained through a fuel reforming reaction. According to the temperature control type monomer reactor provided by the invention, the reaction temperature in the reactor is controlled about 180 DEG C-230 DEG C, preferably 190 DEG C-210 DEG C, and the conversion rate of a carbon dioxide reduction reaction in the carbon monoxide preferable methanation reaction is controlled about 1%-4%; and hydrogen is not largely consumed, the structure is simple, and the cost is low.

Description

technical field [0001] The present invention relates to a temperature-controlled monomer reactor, and more particularly, to a temperature-controlled monomer reactor for use in a fuel cell system (for example, a low-temperature proton exchange membrane fuel cell system). 1. The carbon monoxide preferential methanation reaction of the reaction gas obtained by the fuel reforming reaction. Background technique [0002] It is known in the field of fuel cell systems that there are various fuel types for producing hydrogen, such as alkanes (methane, ethane, etc.), alcohols (methanol, ethanol, etc.), gasoline, diesel, etc. These fuels usually produce hydrogen through fuel reforming reactions (mainly including three reforming methods: fuel vaporization reforming reaction, fuel autothermal reforming reaction and fuel partial oxidation reforming reaction, among which fuel vaporization reforming reaction is the most commonly used) to produce hydrogen, for example , the reaction formula...

Problems solved by technology

[0007] However, the conventional reactor system usually connects multiple reactors in series in steps (for example, it needs to be realized by manual welding, etc.), and usually needs to use more than one heat sink to dissipate heat from the entire reactor system. Too complicated and expensive

Moreover, even if the cascaded design is adopted, the whole reactor system is still prone to local overheating when the reaction gas flow rate changes greatly. Although the conventional reactor system can often make the conversion rate of reaction A reach 100%, the excessive A high temperature will lead to a decrease in catalyst activity and intensify reaction B (making reaction B have a conversion rate of about 5% to about 40%), which will cause a large amount of hydrogen to be consumed and significantly reduce the efficiency of hydrogen production
